Hi All
I have made a routed port on 3560G Switch and defined a pool 172.28.4.62 255.255.255.192 and connected to E1 converter RAD (4E1 to 4 FE) the E1 media is through Microwave on the other end same E1 converter is connected through layer 2 switch and defined a pool as of routed port configured in 3560G switch.
The port is generating lot of giants and after a while it also distrubs other routes ( Port1 to Port 16), configured with Vlan11 and port 22 as routed port.
I have checked the routed port through wireshark the maximum frame size is 1514 and configured the MTU to 1514, giants are not showing any more but after 10 to 12 hours switch gets hang. Either to shut the port or to reload the switch to get switch and other layer routes to be normal.
I have checked speed and duplex settings same as E1 converter. Full duplex. 100 Speed. Can you please guide why switch is not behaving normal. If i shutdown the routed port it is normal.
